Barium was first discovered in 1774 by Carl Scheele from Sweden
Barium was first extracted in 1808 by Sir Humphry Davy from England
Basic Facts
Barium symbol is Ba.
It's atomic number is 56.
Barium has an Average Atomic Mass of 137.33, so it most commonly has 77 neutrons.
Barium is never found in its purest from because it is highly reactive with air.
It is highly reactive because its is in group 2A and Oxygen is in group 6A, through Ionic bonding Barium Oxide is formed, with the Barium cation having a charge of 2-.
Barium is in period 6.
When not in its purest form, Barium is found most commonly as a solid.
Barium is rare but not extremely rare/
Barium has 22 isotopes, 7 are stable. and 15 are radioactive.
Barium comes from the Greek word "Bary" meaning heavy.
Barium is a metal.
Uses:
Barium is not used by itself, but its compounds have many different uses. Bariums compound's uses are:
The Petroleum Industry
Rat Poison
X-Rays of the Digestive System
Bricks
Coating of Fluorescent Lights
Glass Making
Rubber
Gamma Ray Detectors
Batteries in "Next Generation" Energy Efficient Cars
And most famously, The Green Color in Fireworks
All of Barium's compounds are extremely poisonous.
